Question

The quadratic formula can be used to solve an equation only if the highest
degree in the equation is
A. 2
B. 1
O c. 3
O D.O

Answer 1

Answer:

A

Step-by-step explanation:

$x = ((-b +/- (b^2 - 4ac)) / 2a$

The degree in the equation is 2.

The quadratic formula can be used to solve an equation only if the highest degree in the equation is 2.

Answer 2

Answer:

A. 2

Step-by-step explanation:

The quadratic formula is:

$x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$

An equation of the form   $ax^2+bx+c=0$  is only quadratic when $a \neq 0$, therefore it is linear.

Also, by definition, a quadratic equation is an equation where the highest exponent is a square.
